Abstract :
There exists a class of wave digital filters (WDFs) which possesses all-pole characteristics and consists of only modular unit-element (i.e. two-port adaptor with a delay) cascades. The paper proposes an adaptive digital filtering scheme based on a wave-digital structure, which can be used for all-pole system modeling
